Carpenter's mom, Rachel, says the day care immediately took the needle out, wrote up a report and called her. Rachel Carpenter, a nurse practitioner, immediately rushed her daughter to the emergency room.

"It kind of makes me nervous," Aaliyah Carpenter said.

"She had to get tested. She has to get tested in six weeks, and then three months, and then six months," Rachel Carpenter added.

It's unclear how the needle got to the playground, but Rachel Carpenter says someone had to have put it there.

"It's kind of unfair a kid has to go through that because of an irresponsible person throwing a needle in a playground where kids go," Carpenter said.

Pittsburgh's Action News 4 spoke with Pittsburgh City Council president Bruce Kraus. He says no police report was filed in this case.

Kraus says he looked at the patrol logs for that area and knows police check the playground frequently, and always ask for your help.

"If they see anything irregular, or anything out of the ordinary to please log that with 911, to help us help you," Kraus said, "This is a horrible situation that no child should endure."
